The output format should provide a value that matches the one in
the /proc/<pid>/ns/net symlink. This makes it simpler to match the
rpc_xprt and rpc_clnt to a particular container.

Also, when the xprt defines the get_srcaddr operation, use that to
display the source address as well.

Changes in v2:
- Don't bother with NUL termination, just use a length specifier
- Link to v1: https://lore.kernel.org/r/20250122-nfs-6-14-v1-1-164b0b5aa330@kernel.org
